Question

1. Calculate the force of gravitation due to earth on a ball of 1 kg mass lying on the
Mass of earth = 6 x 1024 kg; Radius of earth = 6.4 x 10% km; and G = 6.7 x 10-11 Nm²/kg?)​

Answer 1

Question is only wrong it is 9.8 m/s

Answer 2

Answer

GIVEN :

Mass of earth m1 =6 × 1024 kg

Mass of the ball m2 = 1 kg

Radius of the earth = 6.4 × 106 m

Universal gravitational constant G = 6.67 x 10-11 Nm2kg-

By applying universal law of gravitation:

F = (G m1 m2/r²)

= (6.67 x 10‐¹¹ x 6 × 10²⁴ x 1)/ (6.4 × 10⁶)²

F = 9.8 N
